I know the 3 lens design probably >is better, but is it worth the nearly double price you have to pay for it ? I haven't looked through the new Meade Refractors so I can't address that specifically. However, I would caution anybody about using photographs as a way of judging between telescopes for the following reasons: 1) Photographic use of the telescope is somewhat less demanding (unless we are talking eyepiece projection as in planets) than high power visual use of the optics. You did mention Planetary photography so you may be aware of this. 2) The way the photographs are processed to bring out detail, etc. is likely to have a big effect. (Did they sandwich negatives, etc.) 3) Conditions under which the photographs were taken are likely to be different. Also includes variables like the format of the film used. I for one would love it if the Meade Refractors are great and the mounts are equally good but I for one remain very sceptical. I want to eventually get a 7" Apo Refractor and the thought of paying less has its appeal.
